Lateroconal fascia suspension facilitates retroperitoneal partial nephrectomy.

Background: As the development of various imaging techniques, the incidental detection of renal masses is increasing. Laparoscopic partial nephrectomy (LPN) is the current standard of treatment for renal carcinoma. Though the retroperitoneal laparoscopic partial nephrectomy (RLPN) become the prior choice, the edge of lateroconal fascia blocks the sight and make operation more challenging.

Methods: Between October 2018 and December 2020, the clinical data of 28 cases diagnosed with renal cell carcinoma (RCC) in our hospital was collected and analyzed retrospectively. All patients underwent RLPN and for management of curtain effect, we performed lateroconal fascia suspension (LFS) procedure in all cases with prepared Hem-o-lock clip which bound with 2-0 suture.

Results: RLPN for renal tumor was successfully performed in all cases with no conversions to open surgery and other interruptions. In all cases, the free edge of lateroconal fascia and peritoneum partially blocked the sight of surgeon. We managed the curtain effect successfully and got a satisfying field of view for subsequent surgical procedure. The median operation time was 142 [interquartile range (IQR), 110-164] min, median estimated blood loss was 93 (IQR, 50-100) mL. Median warm ischemia time was 29 (IQR, 22-30) min.

Conclusions: LFS is useful for management of curtain effect. It is a simple, economical and less invasive technique and we can get better efficiency with little consumption.
